目的:指导正确筛选药物流产病例,提高药物流产成功率。方法:对药物流产术后阴道出血时间≥15天的146例进行分析。结果:1360例药物流产者中,阴道出血时间≥15天共146例,药物流产后阴道出血时间延长发生率为10.74%;妊娠3次以上者药物流产后阴道出血时间延长的发生率明显增加,与妊娠次数<3次者比较差异有统计学意义(P(0.05);孕囊≥2cm者药物流产后阴道出血时间延长的发生率明显增加,与孕囊(2cm者比较差异有统计学意义(P(0.05);子宫后位较前位或平位子宫易致药物流产后阴道出血时间延长,二者比较差异有统计学意义(P(0.05)。结论:严格筛选药物流产病例,选择妊娠次数(3次、前位或平位子宫、孕囊(2cm者,可降低药物流产不全的发生率。
Objective: To guide the correct screening of medical abortion cases and improve the success rate of medical abortion. Methods: 146 cases of vaginal bleeding ≥15 days after medical abortion were analyzed. Results: Among the 1360 cases of medical abortion, the time of vaginal bleeding ≥15 days was 146 cases, the incidence of vaginal bleeding prolonged after medical abortion was 10.74%. The incidence of vaginal bleeding prolonged after 3 times of pregnancy was significantly increased, (P <0.05). The incidence of vaginal bleeding prolonged after medical abortion was significantly higher than that of gestational sac (2cm) (P <0.05) P (0.05). The posterior uterine position than the anterior or posterior position of the uterus caused by medical abortion vaginal bleeding time longer, the difference was statistically significant (P (0.05) .Conclusion: Strict selection of medical abortion cases, select the number of pregnancies (3 times, anterior or flat uterus, gestational sac (2cm who can reduce the incidence of incomplete medical abortion.
